Hey what would you suggest to add or change with this combination of fish by the way in a 29 Gallon
2-Red Wagtail Platies
2-gold gouramis
1-silver dollar
1-red tailed shark
1-odessa barb
1-cherry barb
1-pretty sure its called golden algae eater
any ideas are appreciated
Platies: Need to be in a group of either 1 male to 2-3 females, or if you go all males, at least 5, to curb agression.
Gold gouramis: If your talking a member of the Trichogaster genus, 1 male to 2-3 females, though most gouramis species fall to this grouping. They can also get up to 6 inches, which is what a large male I once had reached. He was huge and agressive.
Silver dollars: Are a schooling fish and get up to 8 inches long, so they need a larger tank.
Red tailed shark: Another species too small for your tank
Odessa barbs: A lovely, unusual fish that needs to be in a group. I wish I could keep them. Pretty representative of the barb family.
Cherry barb: Very peaceful, again lovely barb. Should be in a ratio of 1 male per 2 females.
Golden algae eater: Might be the golden morph of the Chinese algae eater, in which case avoid please. Your tank is too small.
Hope this helps a bit. I would go with a species tank of odessa barbs and cherry barbs, that would be so pretty, and not the normal tank that everybody else has. That's what I'd do with the list you gave me.
